For you to be able to have a higher chance of passing a urine drug test, it is important that you should have a total understanding on the concept behind it. Urine drug testing works on the principle that whatever you take into your body, it is broken down, metabolize and absorb by your system. As your body breaks down all the things that you taken in which would include illegal substances, it will leave metabolites which is the by product of the breaking down process. These metabolites are what a urine drug test identifies for you to register as positive on a drug exam.
Urine drug testing is also known as toxicological screening has many uses. It is use mainly to determine the amount and type of illegal substance a person used and to keep track of possible drug dependency. In some cases, it is also use to know the exact cause of drug poisoning.
This is considered as the oldest and most preferred way of examining whether a person uses prohibited drugs or not mainly because it is fast and accurate. The time span of a drug or metabolites to be detectable in a urine sample can be influenced by a lot of factors:
• Amount and Frequency of Use
New users with small doses are detectable only at the lower margin while chronic or long-term users have results that are near or at the upper margin.
• Metabolic Rate
Users who have slower body metabolism tend to have a longer drug detection period.
• Body Mass
The more body mass a person has the slower their metabolism, in addition lipid tissue has the capability to store the metabolites left behind by the breaking down process of illegal substances thus the more lipid tissues your body has the longer the drug detection period is.
The older a person is, the slower their metabolism process thus resulting to longer drug detection period.
• Overall Health
The healthier a person is, the faster their metabolism thus the shorter their drug detection period.
• Drug Tolerance
A person who has established tolerance to a certain drug tends to metabolize the drug faster leading to a shorter drug detection period.
• Urine pH
The higher the acidity of the urine is, the shorter drug detection period it has.
Specimen collection is also an important aspect of Urine drug testing method if you want to get accurate result. In order for you to have a reliable result, you need to have a reliable specimen. In order to achieve this, you need to have a clean and intact specimen bottle to collect your urine. Any breaks or leaks can cause contamination of the urine sample does decreasing its integrity. The time span on which the sample has been taken is also of great importance. It is crucial that you would be able to pass your urine sample within 30 minutes from the moment you collected it. Anything more than that can invalidate your sample thus it would be discarded.
How urine drug tests work
If you are wondering how your urine would be examined, the testing procedure included in this urine drug testing process is classified into two, the immunoassay procedure and the chromatography. The immunoassay procedure is a biochemical test that measures the concentration of a substance in a biological liquid. It uses antibody that would in return reacts to an antigen which is the drugs for a person to turn out positive. The presence of absent of a drug in your urine is indicated by the amount of radioactivity brought about by the binding of the antibody and the antigen thus completing the screening process.
Meanwhile the chromatography is used for confirmation. It is a method that is capable of separating the various components in a biological liquid thus you would be able to identify what particular drug a person uses. There are a number of chromatographic methods namely the Thin-Layer Chromatography, the Gas-Liquid Chromatography, the High-Performance Liquid Chromatography and the Gas Chromatography or otherwise known as Mass Spectrometry.
Urine drug test false positive results
There are only two interpretations of a urine drug test, either positive or negative. A positive result would indicate that a drug is present in the urine. However, it does not mean that a person is immediately under the influence of drugs at the time he or she took the exam. There are times when a person could have a positive result even if they are not using any illegal drugs. This occurrence is called the false-positive result. Certain over the counter drugs and foods can act as interfering factors thus it may affect the result of a drug test. It is important to retake the entire drug testing to confirm whether a person is really using illegal drugs or not.
A negative result shows that a person is not using any drug that can be detected by the urine test. However, it does not also mean that he or she is not entirely using any drugs. It can be that they were not taking any large dose of drugs or that the sample was taken long after they have used any drugs.
Urine drug test results time
Either way, urine drug test still remains the most efficient and most used drug testing kit ever. The benefits it offer is the main reason why this continues to be the number one choice. It is easy to use, it is less invasive and most importantly the result will be out in just a few hours after submitting the sample.
